Seawater reverse osmosis (SWRO) watermakers convert raw ocean water into potable fresh water by forcing high-salinity feed water through semi-permeable RO membranes at pressures between 800 and 1,200 PSI. At that pressure differential, dissolved salts, bacteria, and most trace contaminants are rejected by the membrane surface. Typical salt rejection runs...

Seawater Desalination ResourcesUnderstand the technology in our seawater desalination RO guide, and why boron removal matters for drinking water and irrigation. For lower-salinity inland sources, see brackish water RO; for land-based process water, see industrial RO systems. Learn how recovery rate affects brine and energy use.
